Ok, this one completely appeals to my inner geek. I was trained as a scientist but it's been a while since I've done anything that looks like science. This satisfies that desire to unlock how the world works. In this case, the book is a series of short essays on particular subjects that may sound like daft questions, but have some need to understand the science in order to answer the question. So the title, "how to dunk a doughnut" starts with a discussion of the difference between doughnuts & biscuits and perfects the art of the biscuit dunk. yes, it's light hearted and (scientifically) superficial, but it was a fun read. A lot of the applications are food related - the author being a food scientist - but that at least makes them readily applicable by the non scientist. I imagine any food scientist would find it trivial in the extreme, but for a non scientist or someone at school, it would be a good general informative book. i liked it, but like I said, my inner geek needs feeding every now & then.
